There are a very few rare gem current fund managers who are special. They are special and deserve consideration if they outdistance their benchmarks. Long term performance is perhaps the most significant criteria. I provide a reference that summaries the data in that arena:https://www.forbes.com/sites/kenkam/2019/02/08/investing-with-the-greatest-mutual-fund-managers-2/#775ebd1e2a71
This is good stuff, but caution must be exercised. From the referenced article: “ Out of about 7000 U.S. equity mutual funds in Morningstar's database only 199, roughly 3%, have fund managers who have beaten the S&P 500 by enough to make a difference and outperformed their category benchmark over the past 10 years. “.
Now that is really special, but unfortunately it measures a fleeting characteristic. Investment management is a tough business. Past success doesn’t always translate into future success. Change happens.
However, it just might be worth your time to visit the reference and examine “The List”. You just might improve your portfolio.
